Bettin, a male Human with yellow skin, functioned as both a sniper and an expert in exotic weaponry as part of Wraith Squadron in the year 13 ABY. He participated in a mission on Ryvester that resulted in the death of Imperial Admiral Kosh Teradoc. Bettin placed a transmitter on Mulus Cheems, a gemologist held prisoner by Teradoc, which provided Cheems with directions. Subsequently, the Wraiths baited Teradoc by presenting him with a sculpted gem treasure as an offering. After Cheems verified the treasure's authenticity, Teradoc seized it, but the Wraiths successfully rescued Cheems. Teradoc then retreated to his base, where the sculpture—in reality, an explosive device made of anthracite—exploded.
